Hello, I've been working on a new computer and I hit an error every time I attempt a direct upload from Agisoft Photoscan to sketchfab. In each case the model goes through the 'packaging' stage and then immediately pings back the error message 'Error creating SSL Context 0'. The detailed info simple states 'Response Code: 0'.

I'm sure it's probably some setting on my new machine, but I'm struggling to find a solution and I wondered if anyone had any thoughts?

The computer has been shutdown/restarted multiple times since having this problem.

I have tried the above and not managed to resolve the problem

I'm unsure whether this is a Sketchfab problem or Photoscan Problem or to do with how my computer is set up, my computer isn't new - I have previously used Photoscan to upload over a hundred models to Sketchfab without issue.

New user here, and encountered the same "error 0" as others on my very first model that failed to upload from inside Photoscan to Sketchfab account.

Need specific information as requested below by others.

Hugoandersonwhymark or STAFF: Would really appreciate your filling out the last few steps of your successful resolution on a Windows 10 system. Could you just bullet point the steps you took for "adding the .dll files to the registry"?

Sorry for the delay getting back to you. I'll put a disclaimer here as I'm not a tech whizz and I solved my issue via a series of Googles and tinkering. I've rechecked what I did at the end, so here so goes:

As I said previously, just installing Win32OpenSSL did not seem to work for me so I manually added the .sll files by:

Opening the Win32OpenSSL zip file.

Copying the .dll files (libeay32.dll and ssleay32.dll)

Pasted these in the following locations: Windows C:/Windows/system32 and Windows C:/Windows/sysWOW64

I immediately tested an upload and the issue was fixed. I can't say if there's a better way of doing this, but I've had not issues as a result.

Thanks for the additional information, Hugoandersonwhymark. Just two more clarifications would be helpful.1) At the Win32OpenSSL web page, there are two versions of installers, 1.1.0 and 1.0.2. Could you identify the version you used for the two DLL files?

2) Both versions are distributed as EXEs. I don't see a ZIP archive for distribution. Did you run the EXE, or perhaps access a ZIP file at another location?
